First time out with a 6 BR Ackley

I almost forgot about that. @Torge was about in tears LOL!

I'll have to hear the story sometime lol

Very cool. I really do want to discuss these tests but I just want you to realize they are discussions, not conclusions about 1K shooting or anyone's expertise (or who wins etc etc). I am genuinely interested.

I am not a 1K shooter. I have no resume or pedigree in shooting. I am a nobody in shooting. I do however have a Six Sigma Black Belt in process analysis and troubleshooting and have been a mechanical engineer working in manufacturing and automation for two decades, and I just have to say these tests are totally inconclusive by any statistical measure. Not enough data points. No process controls. Too many variables. No way to determine capability of any part of the process. And certainly does not even include conditions.... which is by far the most outcome effective portion of the analysis. Other than it does appear the process is totally out of control.

One or two data points are not a trend. I suppose it is the nature of the beast. To do real testing the barrel would be shot out. But to do a cartridge caparison one would need to do head to head multiple data point testing to prove capability. There are statistical tools out there to solve problems exactly like these, and they do work. Six Sigma has computer programs for testing exactly like this.

I get what you’re saying as a person who has utilized path analysis, multilevel modeling, structural equation modeling, regression, etc. when analyzing data. What I have come to appreciate in the precision shooting world is that many of the competitive shooters I encounter shoot A LOT. And when you shoot a lot, trends emerge. These trends are shared among each other and more shooting is done. After more shooting is done, the variable(s) that impact the trend become apparent. Then a lot more shooting is done to see how the factors covary. And then more shooting is done and a new trend emerges. The cycle continues. In my view, this whole thing is an experiment and the people who shoot a lot communicate with each other about the trends and testing. Granted, this isn’t a well-controlled experiment published in a top tier scientific journal, but this experiment yields reliable and repeatable results. It’s great to be part of it and see the communication. However, the scientist in me wants to win the lottery and do endless highly controlled testing. Lol! Have you seen the “Houston warehouse” write up? Interesting stuff but more related to the short range. It would be cool to have a 1000 yard tunnel to tinker around with variables

Lol, if I won the lottery my wife would buy me a 1000y underground tunnel just to keep me and the noise away.
